Ten minutes passed, and the four sword ghosts kept rushing around the zombie crowd every second.

They are like bosses in the game with their own burning aura, and as long as they pass by, they will take a lot of damage to nearby enemies.

"Command, are the statistics out?" Zhou Dong fiddled with the headset and began to calmly walk up the stairs to the rooftop.

The few helicopters that have been hovering over the city are all live broadcasters and observers.

The footage they took was synchronously transmitted back to the command, and the command immediately had professionals to count the relevant data.

"In an environment where zombies gather in large numbers, regardless of the time it takes to find enemies, they can inflict heavy damage on about three zombies per second, and now more than 6,000 zombies have been incapacitated." Stats came from Command.

Zhou Dong was not surprised to hear this result, it was expected.

Crushing brainless zombies with steel monsters, if you can't achieve this record, it will be incredible.

According to the current progress, four sword ghosts can slaughter at least 30,000 zombies in an hour, which is only four.

And the current reserve of knives and ghosts in the arsenal on Amirada Island is - a whole hundred!

If more sword ghosts are put in, by dawn, the zombies in the entire city should disappear at least eighty percent.

However, that means that in the ideal case, once there are fewer zombies, the efficiency of the sword ghosts will decrease a lot with the time spent looking for them.

"Sir, please instruct me if I want to put in more sword ghosts?"

"It's not time yet, the first generation of sword ghosts are not those big zombie opponents, focus on cleaning them up first, and then invest in the remaining sword ghosts."

I want the Knife Ghost to slaughter zombies in this city at will, but there is still one last hidden danger to help them deal with.

That's it – the big zombies.

Because of their size, these four sword ghosts can only crush large zombies below three meters.

And the big zombies that exceed this height have the power to probably break the knife ghost with one punch.

It's not that they haven't thought about making a larger knife ghost robot, but the underground factory is currently only forming a small automatic assembly line, and the functional robots of other projects are also under construction, so it is impossible to pull all the resources out of the knife ghost, not to mention that Zhou Dong's mastermind plan also occupies a lot of human and material resources.

Under the rush of production, it is quite good to be able to reach the current level.

"All the guards loaded the explosives onto the helicopter, in groups of two, each looking for zombies that were more than three meters tall, and threw explosives from a high altitude to destroy them, taking care to maintain the height."

"Special warning, giant zombies that are more than ten meters tall have child-level intelligence, be careful to pay attention to their hand movements, don't be hit by throwables, plan b begins!"

Zhou Dong's new order was issued, and the city now cultivated forty-five big zombies, of which thirteen were giant zombies that evolved after eating hundreds of humans.

Even the ten-meter-tall giant zombies had beta-level strength, and Zhou Dong didn't plan to help them personally.

After all, even if it has the strength of a beta-level mutant, such a giant zombie only has the intelligence of a child.

For these guards, as long as they do not underestimate the enemy, they can basically complete the task without injury.

If they can't even do this, Zhou Dong really has no interest in leading a group of survivors whose intelligence level is not as good as that of young children to build a new world after the disaster, so that they can die early and be reincarnated.

At two o'clock in the middle of the night, the zombies were almost cleared, but they also lost three helicopters and twelve people.

At that time, there were three helicopter pilots, and through their crushing records, they thought that these zombies were actually easy to bully.

So, carelessly, they didn't heed Zhou Dong's reminder, and lowered their height, wanting to hunt down those big zombies that were several meters high.

Then near the tall building, immediately a licker will break through the glass and suddenly jump from mid-air and pounce on the helicopter.

They desperately threw down the helicopter with their flesh and blood, and they were only controlled by instinct, just wanting to eat the fresh meat, even regardless of their own life and death.

Or maybe there's a giant zombie that suddenly appears from the corner of the building, grabs a car and throws it at the helicopters.

The three helicopters were basically killed too carelessly, which can be regarded as a lesson for all the soldiers and guards in the archipelago, as for whether they will have long experience, Zhou Dong doesn't know what they think in their hearts.

At around two o'clock in the middle of the night, the remaining knife ghost robots were put into the city of San Francisco one after another.

The killing, which lasted until dawn.

On the rooftop of the town hall building, the concrete floor is dyed golden by the sun.

Zhou Dong bathed in the morning sun, looking at the whole city, it was much cleaner.

After a night of slaughter, less than 10 percent of the city's zombies remained.

A hundred Blade Ghost Robots are constantly patrolling the streets, and their spider feet can also allow them to enter the ground floor of the building on a flat enough ground.

Through the helicopter's incessant circling broadcasts, most of the survivors in the city knew that help was coming.

They walked out of their hideouts, and groups of survivors looked out from all corners of the city to find that the streets were now empty compared to the zombies of yesterday and last night.

Overjoyed, they immediately began to pack their belongings and prepare to escape from this zombie city.

And when they are chased by zombies, they immediately follow the radio instructions and lead them into the street.

At this time, the sword ghosts who were scattered throughout the city of San Francisco and divided the city into a hundred areas would quickly rush over from nearby to protect them.

Under the highly efficient zombie cleanup plan, there are occasionally a few zombies hiding in the building to escape, they obviously survived, but they look so lonely and pitiful.

According to the prompts on the rescue announcement, the survivors went to the rooftop of a nearby building, and then used various objects to put out SOS distress signals.

Thirteen helicopters began rescue work at dawn, and groups of survivors were being transported to Angel Island.

Just like how the people of this continent treated immigrants of different colors in the old days, Angel Island's system is now at least ten times more severe.

Because the staff on Angel Island are all people with families on Amilada Island, they will never allow anyone who may carry the virus to enter the island.

At the same time, in order to prevent people from abusing their power and viciously persecuting these immigrants on trial, such as coercing them with money and body, Zhou Dong also has a set of strict rules and regulations waiting for those greedy things.

The island society under his control will never be a utopian paradise of happiness, but it will never allow those filthy crimes to appear.

This is not good, but the long-term management vision and means that an excellent ruler should have.
